Egg Pipes

The player is seated in a clear glass tank like a bath on the floor, with three pipes pointed towards them from above and diagonally from the sides. These pipes run into a tangle of criss-crossing pipes on the room's walls and ceiling, ending at a large tank of egg-like stringy yellow gunge mounted to the ceiling. The rest of the team have to follow the pipes and identify the valves to turn off before time runs out to save their friend from being gunged.
